Jan Wassenberg 627cc04db9 Decouple MatMul from gemma-inl: precompile for all input types 
Call MatMulStatic instead of MatMul.

Also fix build error due to Highway's Lanes not being constexpr.

Jan Wassenberg 35fdf848c7 Cascaded summation for Softmax 
This can affect generation results after a few hundred tokens.

Also remove profiler from DecompressAndCall, use Add instead of +=,
use PackedSpan for args and remove alignment requirement.
Changing accumulation order in AssimilateCascadedSums updates dot_test thresholds.
